New report: How the pandemic compounds education pipeline challenges

The Western Interstate Commission for Higher Education (WICHE) has released new analysis based on updated data that suggests potentially greater long-term public school enrollment challenges, as well as recommendations for educational leaders and policymakers as they continue to grapple with the impacts of COVID-19 on the K-12 pipeline. This new analysis focuses on public school enrollment changes...

Closed loop for circular economy: New polymer recycling strategy ensures both high stability and complete recyclability

The ever-increasing generation of plastic solid waste has resulted in global plastic pollution both on land and in the oceans. Projections show that plastic waste will double in the next 20 years, causing further environmental problems. Large amounts of plastic waste are, at present, incinerated or deposited in landfills. This not only degrades the environment but also depletes valuable resources.

New study uncovers unprecedented declines in iconic kelp forests along Monterey Peninsula

A new study published in PLOS ONE provides novel documentation of kelp forest decline along the west coast of the U.S. and Mexico in response to the 2014–2016 record-breaking marine heatwave, along with evidence of regional recovery. Using Kelpwatch.org, an open-source web tool used to visualize and analyze nearly 40 years of kelp canopy dynamics data derived from satellite imagery, the study...

Hard-right social media activities lead to civil unrest, says paper

Does activity on hard-right social media lead to civil unrest? With the emergence and persistent popularity of hard-right social media platforms such as Gab, Parler, and Truth Social, it is important to understand the impact they are having on society and politics. Previous research on the relationship between social media use and subsequent offline behavior has been ambiguous. While some studies...

Dairy sector boasts 100 years of successful herd data collection

The U.S. dairy industry operates a comprehensive data collection program that records herd production information from farmers nationwide. The program provides crucial input for cattle breeding and genetics, and its cooperative structure ensures benefits for producers and scientists alike. A new study from the University of Illinois explores the program's century-old history, highlighting its...

Study: SARS-CoV-2 can alter genome structure of our cells

People infected with SARS-CoV-2, the virus that causes COVID-19, may experience genome structure changes that not only may explain our immunological symptoms after infection, but also potentially link to long COVID, according to a new study by researchers at UTHealth Houston.

Hubble monitors changing weather and seasons of Jupiter and Uranus

Ever since its launch in 1990, NASA's Hubble Space Telescope has been an interplanetary weather observer, keeping an eye on the largely gaseous outer planets and their ever-changing atmospheres. NASA spacecraft missions to the outer planets have given us a close-up look at these atmospheres, but Hubble's sharpness and sensitivity keeps an unblinking eye on a kaleidoscope of complex activities over...

Eco-friendly foam can insulate buildings without warming the globe

Rigid foam boards used to insulate buildings can prevent energy loss, making homes more efficient at keeping warm or cool. The advantages in energy efficiency, however, are undercut by environmental concerns over polystyrene products. Blowing agents used in foam production, such as hydrocarbons and hydrofluoroolefins, end up in the atmosphere and contribute to global warming.

New reports outline bold goals for U.S. bioeconomy

On March 22, the White House Office of Science and Technology Policy released a series of five reports authored by federal agencies, including the U.S. National Science Foundation, outlining bold research and development goals for the U.S. bioeconomy.

How salt can taste sweet: The myriad mechanisms of taste perception

Humans perceive five basic taste sensations: sweet, umami, bitter, salty, and sour. Specific foods trigger taste recognition of these sensations through the activation of different receptors in our taste buds. In the case of table salt, the concentration is also an important factor in determining taste.

Study: Lithosphere architecture controls the formation of orogenic gold deposits

Professor Zhang Haijiang from the School of Earth and Space Sciences, University of Science and Technology of China (USTC), in collaboration with academician Hou Zengqian from the Institute of Geology, Chinese Academy of Geological Sciences, and Professor Wang Qingfei from the China University of Geosciences (Beijing), have discovered that the lithosphere architecture characterized by crust-mantle...

Habitat will dictate whether ground beetles win or lose against climate change

The success of North American crops from corn to Christmas trees partly depends on a relatively invisible component of the food web -- ground beetles. Nearly 2,000 species of ground beetle live in North America. New research shows that some of these insects could thrive while others could decline as the climate changes. The team found that the response will largely depend on the species' traits...

Global natural history initiative builds groundbreaking database to address 21st century challenges

A group of natural history museums has mapped the total collections from 73 of the world's largest natural history museums in 28 countries. This is the first step of an ambitious effort to inventory global holdings that can help scientists and decision makers find solutions to urgent, wide-ranging issues such as climate change, food insecurity, human health, pandemic preparedness, and wildlife...

Eye color genes are critical for retinal health

Metabolic pathways consist of a series of biochemical reactions in cells that convert a starting component into other products. There is growing evidence that metabolic pathways coupled with external stress factors influence the health of cells and tissues. Many human diseases, including retinal or neurodegenerative diseases, are associated with imbalances in metabolic pathways.

Can insights from the soapbark tree change the way we make vaccines?

The medicinal secrets of the Chilean soapbark tree have been laid bare, unlocking a future of more potent, affordable, and sustainably sought vaccines. Researchers have taken a major step forward in addressing this problem, by using a combination of genome mining and bioengineering techniques to produce saponin-based vaccine adjuvants in the laboratory without harvesting material directly from...

Compact x-ray laser would shrink billion-dollar machines to the size of a room

When the first x-ray free-electron laser (XFEL) opened in 2009 at SLAC National Accelerator Laboratory in California, it provided a new way to look at the atomic-scale world, revealing details about biochemical processes such as photosynthesis and exotic materials such as superconductors. But since then, only four other such billion-dollar facilities have been built worldwide, and getting...

The journey of a carbon atom: From space, NASA's PACE mission detects carbon in the sky, land and sea

Whether in plants or animals, greenhouse gases or smoke, carbon atoms exist in various compounds as they move through a multitude of pathways within Earth's system. That's why NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission—scheduled to launch in January 2024—was designed to peer down at Earth from space to see those many forms of carbon in a way no other satellite has done...

Many genes, rather than a 'miracle gene,' are involved in plant resurrection

Some plants can survive months without water, only to turn green again after a brief downpour. A recent study by the Universities of Bonn and Michigan shows that this is not due to a "miracle gene." Rather, this ability is a consequence of a whole network of genes, almost all of which are also present in more vulnerable varieties. The results have already appeared online in The Plant Journal.
